Built-up welding welding gun 7 compresses arc plate 8, location nut 9, rack beam 10；The rack beam 10 is a box, with bracket upright post 1
Group weldering is an entirety；Four lead screw sleeves 5 are uniformly weldingly fixed on four sides of 10 box of rack beam, adjusting screw 4 one
End is connect with manual turntable 6, and the other end is linked together with compression arc plate 8 by location nut 9, is passed through and is adjusted manual turntable 6
Compression arc plate 8 is driven to realize that workpiece is fixed.
The application method of the fixed device of vertical horizontal position welding built-up welding:
1. rotating four manual turntables 6 respectively counterclockwise makes its retrogressing, sufficient space bit is provided for the workpiece of fixation to be held
It sets；
2. 90 ° of bend pipes 2 of overhead traveling crane handling and 3 main ring of the straight tube one-piece machine member welded of seam are to the centre bit of 10 box of rack beam
It sets, guarantees that workpiece stablizes movement during handling；
3. as shown in Fig. 2, rotating clockwise manual turntable 6, forward by adjusting screw 4 when workpiece is moved to and formulates position
Transmission compresses arc plate 8；
4. if repeating the above process, which makes its excess-three compress arc plate, makes it when one of compression arc plate 8 starts to be bonded with workpiece
It is bonded with workpiece；
5. symmetrical fastening compresses arc plate 8, guarantee the uniformity and workplace vertical degree of piece-holder stress；
6. adjusting the position of built-up welding welding gun 7 when piece-holder fixes and reaches requirement, carrying out horizontal position welding built-up welding.
The present apparatus integrally steadily fixes 90 ° of bend pipes and straight tube, realize vertical horizontal position welding weld deposit process stability and can
By property, and it can realize that different diameter specifications workpiece is fixed in a certain range, it is versatile.
The present invention uses TIG argon arc-welding built-up welding, and surfacing layer quality is stablized, greatly improves oil gas entrance and oil gas vent is curved
Head and straight tube or flange rim built-up welding efficiency and qualification rate, it is significant to the manufacture of the component.
